Well, it could be about Naruto having to deal with the strict and fiery nature of Akainu as his father. Maybe Naruto has to adapt to a more military - style upbringing while still holding onto his own ninja values.
The plot might involve Naruto struggling to fit in with the Akainu - influenced family or group. He could be constantly at odds with Akainu's ideas, yet slowly learning some useful skills from him. For example, Akainu's strong sense of justice, though different from Naruto's ninja world's concept, might shape Naruto in a new way. And there could be conflicts with Naruto's friends who don't trust Akainu or his family. Also, Naruto might have to face enemies who target him because of his relation to Akainu.
One possible plot could be that Akainu attacks the Straw Hat's new island, endangering Luffy's friends. Luffy, filled with rage, challenges Akainu. After an intense battle, Luffy discovers a new form of his Gear ability that allows him to withstand Akainu's magma and finally defeat him.
Naruto's character would likely become more complex. He might develop a harsher edge due to Akainu's influence, but still retain his core kindness.
One common theme is the clash of ideologies. Akainu has a very strict and uncompromising view of justice in his original story, while Naruto has a more forgiving and rehabilitative view. So when they interact in fanfiction, this clash often forms a central theme.

Well, it could be about Naruto having some hidden connection to Scorpion. Maybe Scorpion had a secret relationship and Naruto is the result.

The plot might involve Naruto having to deal with the stigma of being the'son' of Sasori.

The plot might revolve around Naruto being ostracized because of his relation to the 'son of scar' title.

Well, it could be about Naruto growing up in the Hyuga clan. Maybe he discovers his true parentage early on and has to deal with the expectations and politics of the clan. He might learn the Gentle Fist technique in a different way than Neji or Hinata.
Well, it could be about Naruto having some of Azula's traits. Maybe he has her strategic mind. For example, in battles, he could use her style of planning and outwitting opponents.
